How does Chapter 28 define the qualities of a Sadguru, using Sai Baba as an example?

Chapter 28 portrays Sai Baba as the quintessential Sadguru. It begins by stating that Sai dwells in all beings, from Brahma to the smallest insect, and is complete in Shabda-Brahma, showing signs of the Supreme Being. The text highlights a Sadguru's unique compassion, noting that while a father gives birth to a body that will eventually die, "The Guru removes both birth and death; that is additional compassion." This profound ability to liberate followers from the cycle of samsara is presented as a defining quality. As explained in this chapter, a Sadguru is established in one's own true nature and has the ability to impart teachings to disciples.
